Answer:

Kaitlin bought 48 yards of ribbon.

Step-by-step explanation:

Hey! Let's help you with your question here!

So, let's start by figuring out what we know and what we need to figure out. First of all, we started with $15 and ended with $4.92. We also know that the price of the ribbon is $0.21 per yard and we need to figure out how many yards of ribbon she purchased.

In order to figure this out, we first want to know the difference in the price between what we started and what we ended up with. So, we can subtract! It would look like this:

[tex]15-4.92=10.08[/tex]

So, we figured out that the difference in the price is $10.08, but how do we find out how many yards of ribbon Kaitlin bought? Well, since we know that it is $0.21 cents for a yard of ribbon, we can just take the difference in price and divide it by how much a ribbon cost for a yard of it. So it would look like this:

[tex]10.08/0.21=48[/tex]

We have a nice whole number and that's our answer! Therefore, Kaitlin bought 48 yards of ribbon.

Mathematical Way:

To do it in a more mathematical way, we can put it in the form of a formula. We know that the end total is $4.92 and the initial is $15. We also know that it's $0.21 cents per yard of ribbon but we don't know how many yards she bought. We can let the number of yards she bought represent x in the formula, so we have:

[tex]15=0.21x + 4.92[/tex]

This formula makes sense because we start with $15 at the beginning, so we want to add $4.92 from 0.21x because the end total is the remainder of how many yards Kaitlin bought. The process is essentially the same as the method above. If we were to solve the formula, it would give us the same answer:

[tex]15=0.21x+4.92[/tex]

[tex]15-4.92=0.21x[/tex] - Moving the 4.92 over to the left side, beginning to isolate x.

[tex]10.08=0.21x[/tex]  - Subtracting $4.92 from $15.

[tex]\frac{10.08}{0.21} =\frac{0.21x}{0.21}[/tex] - We divide by $0.21 to solve for x.

[tex]48=x[/tex]

And here, we get the exact same answer, 48 yards of ribbon.

SOLUTION

Let the electric bill for September be x.

October's bill is $2.65 less than the September bill

This means that October's bill = x - 2.65

September + october bill = $174.65

That means that x + x - 2.65 = 174.65

Now let's find x which is september's bill

So September's bill is $88.65, now each student pays

So each student owe $29.55 for the month of September

Complementary angles - The smaller angle is 24 degrees in size.

what are complementary angles?

Angles that add up to a precise 90 degree angle are said to be complementary. For instance, 30 degrees and 60 degrees are complementary angles.

Let x equal the first angle's measurement for the sake of explanation.

Let y be the size of the first angle's complement.

One angle, which we'll refer to as y, is 18 more than twice as large as another, x.

y = 18 + 2x

Complementary angles add up to 90 degrees.

x + 18 + 2x = 90

By substituting for y,

we get x + 18 + 2 x = 90.

Putting like phrases together and taking 18 off on both sides...

3x + 18 = 90

     - 18    -18

3x = 72

By dividing both sides by 3, you get

3x/3 = 72/3

24 degrees is the angle between the two that is smaller. and the other angle would be,

y= 18+2x

=18+2(24)= 66 degrees.

Explanation

Let x be yesenia's unit rate

If yesenia knits 21 centimeters of a scarf every week, then;

21 cm = 1 week (7 days)

To determine the amount for her knitting in a day, we can write;

x = 1 day

Divide both expressions

21/x = 7/1

Cross multiply

7 * x = 21

7x = 21

x = 21/7

x = 3

hence yesenia's unit rate is 3cm per day

- Recall that;

21 cm = 1 week (7 days)

Let y be the length of the scaf sfter 18 days, To get the length of the scarf, we can write;

y = 18days

Divide both resulting expressions;

21/y = 7/18

7y = 21 * 18

y = 3 * 18

y = 54cm

Hence the scarf will be 54cm longy

Statement Problem: Mr. Bensoua buys 3 bags of Flaming Hot Cheetos for every 4 bags of Takis. He buys a total of 14 bags of chips. If the Flamin Hot Cheetos cost $2 per bag and the Takis cost $2.50 per bag, how much did Mr. Bensoua spend on all of the chips?

Solution:

When Mr. Bensoua buys 4 bags of Takis, he buys 3 bags of Flaming Hot Cheetos.

When he buys another 4 bags of Takis, he buys 3 bags of Flaming Hot Cheetos.

At the end, he buys 8 bags of Takis and 6 bags of Flaming Hot Cheetos and that makes it a total of 14 bags of chips.

The cost of Takis per bag is $2.50, the cost of 8 bags of Takis is;

The cost of Flaming Hot Cheetos per bag is $2., the cost of 6 bags of Takis is;

Answer:

x = - [tex]\frac{5}{2}[/tex] , x = - [tex]\frac{4}{3}[/tex]

Step-by-step explanation:

6x² + 23x + 20 = 0 ( factorise the left side )

consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 6 × 20 = 120 and sum = 23

the factors are + 8 and + 15

use these factors to split the x- term

6x² + 8x + 15x + 20 = 0 ( factor the first/second and third/fourth terms )

2x(3x + 4) + 5(3x + 4) = 0 ← factor out (3x + 4) from each term

(3x + 4)(2x + 5) = 0

equate each factor to zero and solve for x

2x + 5 = 0 ⇒ 2x = - 5 ⇒ x = - [tex]\frac{5}{2}[/tex]

3x + 4 = 0 ⇒ 3x = - 4 ⇒ x = - [tex]\frac{4}{3}[/tex]

We have a point (4,-9) it moves to (9,-14)

(4+x = 9, -9+y= -14)

x = 9-4

x = 5

y = -14 +9

y = -5

We are moving to the right 5 and down 5

We want to move the point (-9,-8) exactly the same way

(-9+5, -8-5)

The exponential function is f(x) = 64·(1/2)ˣ which can be used to find the number of teams left after a round.

An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.

Given that 64 teams qualify for a basketball tournament. After each round, half of the teams are eliminated.

Because it is an exponential function, f(x) will reach 0 as x increases, allowing us to construct the following table of values:

x    f(x)

0    64

1     32

2    16

3     8

4     4

5     2

6     1

At that point, 64 teams are in the tournament, and the total number of teams (from this point forward)

Therefore, half of the teams are eliminated after each round and the exponential function is:

f(x) = 64·(1/2)ˣ

The percent of increase in the cost of the perfume is 29.86%

What is percentage and how can it be calculated?
A percentage is a figure or ratio that can be stated as a fraction of 100 in mathematics. If we need to determine a percentage of a number, multiply it by 100 and divide it by the total. So, a part per hundred is what the percentage refers to. Percent signifies for every 100. The sign "%" is used to denote it. No dimension exists for percentages. Thus, it is referred to as a dimensionless number.
Mathematically,
Percent of increase = [(Final value - Initial value)/(Initial value)]×100

Given, the final value of the perfume at purchase = $41.49
Also, the initial value of the perfume as assessed = $31.95
Therefore using the formula established in the literature above,
Percentage increase = [(41.49 - 31.95)/31.95]×100 = 29.86%
Thus, the percent of increase in the cost of the perfume is 29.86%
